Abstract
A new concept of heart valve prosthesis, based on the use of textile material was developed in order to improve the characteristics of a prosthesis. A woven fabric stentless prosthesis obtained with polyester microfibers or microfilaments was manufactured and tested. The flexibility of textile in the opening phase, offering low resistance to blood flow by an easy folding of the microfibers tissue, was observed. The influence of the textile on the flow accross the aortic sinuses has been analyzed. It was shown that the weaving gives the tissue a macroscopic behavior close to the one of the collagen-elastin valve tissue structure. The flexibility of textile in closing phase shows good coaptation of the cusps leading to good floodtightness.
